DEKOUNTABLE am STRUCTURE FOR WHEELS.

Application filed larch 22, 1921. Serial No. 454,396.

To all whom it may concern:

Be it known that I, WJLLIAM BAiumn, a citizen of the United States, residing 1n the city of New York, county of Kings, State of New York, have made, a certain new and useful invent-ion in Demountable Rim Structures for Wheels, of which the following is a specification.

This invention relates to fixed structures for wheels. It includes subject-matter divided from my application Serial No. 369,- 461, filed March 29, 1920 and is a continuation in part of said application.

The object of the invention is to provide -.a structure which is simple, economical to manufacture, and efiicient, for demountably securing tire rims of various standard types upon the same wheel.

A further, object is to provide a fixed rim structure for wheels which is universal in its adaptation to accommodate various standard types of demountable tire rims at present in use.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of'parts, all as will be more fully' hereinafter set forth, as shown in the accompanying drawing, and finally pointed out in the a pended claims.

Referring to the rawing, Fig. 1 is a view in section, on the line 1, 1, Fig. 3, through a portion of a wheel showing a form of demountablerimstructure embodying the principles of my invention. Fig. 2 is a similar view showin another form or type of demountable. w eel rim adapted to the rim,mounting of my invention.

Fig. 11 1s a broken View in inside plan of the meeting ends of a tire rim or band, showing one form of interlocking lugs ordinarily employed in connection with tire runs.

Fig. 12 is a broken View in section on the line: 12, 12, Fig. 10.

Various standard forms or types of demounta'ble rims are at present in general use for automobile or other wheels, but,-so far portion of the fixed rim portion 5 as I am aware, each type of rim requires its own special form of fixed rim upon which 1t may be demountably mounted and secured. TlllS practice-is objectionable for the adapted to receive one type of vdemou'ntable reason that a fixed rim structure which is 89 to obtain the particular type of rim to which a fixed rim is adapted at a time and place where a rim is needed.

7 It is amongthe special purposes ofmy present invention to provide a fixed rim structure which is universal in its adaptaac tion to receive and accommodate various types and forms of rims. While I have shown and will describe my Invention as applied to sheet steel disk vention is not to be limited or restricted in this respect as it is capable of being readily utilized in connection with wood and other types of wheels.

In the drawing, reference numeral 5 desig- 1 nates the fixed rim upon which a tire rim is to be demountably mounted. In the case of a disk wheel, the wheel, in one form, is made up of the disks 6, 7, and the fixed rim 5. is formed in anan'nular flange of one we cat the wheel disks. The fixed rim also exthat my inwill iii

teriorly shaped to demountablymeceive thereon the rims which carry the tire.

In order to receive and accommodate various types of rims, the fixed rim 5 is formed with a plurality of annular shoulders'successively arranged or disposed in its transverse width, and in the region of one edge thereof, namely, in the region at its free edge. In the structure shown in Figs. 1 and 2 two such annular shoulders 8, 9, are formed in the fixed rim said shoulders respectively adapted to form lateral bearing seats or shoulders against rim may be demountably clamped. For instance, in Fig. 1, I have shown one type of rim which is in common use and which is formed with a shoulder 11 on its interior surface, and which, in a structure embodying my invention, seats laterally and is clamped against the annular shoulder 8 of the fixed rim. In Fig. 2 I have shown another common type of wheel rim which is formed with an edge shoulder 12 and which, in a structure embodying my invention, seats against the annular shoulder 9 of the fixed rim.

Thus, by the structure shown, the same fixed rim will receive and accommodate various types of demountable r'uns.

The rim, whether of the one or another type, may be demountably clamped upon the fixed rim in various ways. I have shown unexceedingly simple and efiicient structure wherein, after the rim is applied to the fixed rim and seated at one edge or side against one or another of the annular shoulders formed in the fixed rim, according to the type of rim, it is clamped in place by means of a retaining ring 13, which is applied against the other edge or side of the rim. This ring is detachably held in ap' lied position by means of clips 14, carried y stud bolts 15 mounted in the wheel body adjacent the fixed rim, nuts 16 threaded onto the bolts 15 serving to clam the parts together. The cli s are forme with elonygated o enin 1 therethrough through which t e bots 15 extend. By backin oil the nuts the clips are released an may then be displaced sufliciently to enable the retaining ring 13 to be removed therehy permitting the rim to be removed from the fixed rim and replaced thereon when necessary or required.

in case of a disk wheel, one of the disks may be formed with an annular shoulder 18, adjacent the mountin of the stud bolts 15, and this shoulder iii in retaining the clips 14;"1'1 clamping position when clamped by the nuts '16.

lit is the usual custom to construct demountable tire rims in the form of bands or rin suitably shaped on the outer surface t erect to receive the tires. Ordi- O nature 0 my mvention, and a construction llttlflly the tire rims or hands are split transwhich a different type of amuse versely to facilitate the application thereto and removal therefrom of the tire. In the case of split rims it is the custom to apply interlocking lugs to the abutting ends of the split rim to prevent relative lateral displacement of said ends. These lugs usually are riveted to the inner surfaces of the split ends of the rim. They are'not usually of uniform size or location in the various types and forms of rims, and hence each type or form of rim requires a fixed rim with a deression transversely across its exterior surace to receive and accommodate the lugs of the particular form of rim to which it is adapted.

It is also among the special purposes of. my present invention to provide a fixed'rim structure which is adapted to receive and accommodate detachable split tire rims whatever may be the size or location of the interlocking in at the ends thereof. In carrying out t is feature of my invention 1 construct the fixed rim with a plurality of seats or depressions to extend transversely partially across the exterior surface thereof, to respectively different transverse distances and of respectively different sizes or areas.

Referring to Figs. 4 to 12, the rim ends 20, 21, have the interlocking lugs 22, 23, applied to the inner surfaces thereof. To accommodate these lugs and permit the quick and eas application of the demountable rim to an its removal from the fixed rim, whatever ma be the size and relative location of -said lugs, I form the fixed rim with a plurality of transversely disposed seats or epressions two of which are shown at 24, 25, of relatively different distances transversely across the exterior surfaces of the fixed rim, and of relatively different areas, and at various points around the periphery of the fixed rim. These seats or depressions ma be conveniently pressed into the extenor surface of the fixed rim by suitable die operations in an suitable manner. It will be understood, 0 course, that in mounting a rim upon the fixed rim the particular seat or depression 24, 25, will be selected to accommodate the particular tire rim em-.

ployed. It will be seen by comparing Figs. 6 and 7 that the seats or de ressions 24, extend relatively different istances across the fixed rim from one ed e thereof towards the other edge, and the epressions are of relatively di erent dimensions as clearly indicated in Fig. 4.

From the foregoing descri tion it will be seen that I provide an excee ingly simple, economical and eflicient fixed rim structure in which various types or forms of rims may be received and accommodated, and demountably mounted thereon.

Hav" now set forth the objects and 2. In a demountable rim structure for metal disk wheels, a wheel disk having a fixed rim member, said fixed rim member having transverse depressions, a plurality of seating portions in its exterior surface, and
